Generally no. Windows 7 disables defragging on an SSD. You can force windows to run defrag on an SSD. It takes a long time and there's generally no reason to do this. The following article shows that there's very little performance degradation in a fragmented SSD.
Windows 8 and greater will run TRIM on SSDs. You'll notice in the Defragment and Optimize Drives tool, that the Optimize button is enabled on SSDs and clicking it will run TRIM. Whereas the Optimize button on a mechanical drive will run a defrag.
